How can you tell if the TPMS sensor is bad? - 2006 GMC Yukon

TPMS, or Tire Pressure Monitering System, tends to be very touchy when it comes to the pressure of the tire. I have seen some sensors not read low until the tire was almost PSI from what it should be, and I have seen some tires read low when they were only 1 PSI low. Are you sure its bad? Although its now standard to have TPMS on all vehicles, most only use a dummy light to show that there is a pressure issue with a given tire. So that could just be the issue here, that a tire is a tad bit low on pressure. I would check that first.

If adjusting the pressure doesn't fix things, your next step would be to take it to the tire shop, as there is no way for the consumer to know which tire sensor is bad, short of seeing the sensor snapped off inside the tire.

Hope this helps!!

You will need to either have the TPMS sensors checked with a TPMS scan tool or use a high end scan tool to check for codes in the TPMS system. the most common problem is a week or dead sensor in the tire. A good TPMS scan tool will tell you if this is the problem.

Yes there is ,and you already had that done & were told
of the issue

Replace the bad TPMS Tire Valve & Stem

You cannot, it takes a special radio communication tool that talks to the sensors one at a time to see what they are doing. The tool is not cheap and most dealers charge to have your sensors checked. The best thing is to find a tire shop that has one.

Check all tire pressures INCLUDING
THE SPARE TIRE

You either have low tire pressure in a tire
A bad tire pressure sensor in a wheel
Or just need to reset the TPMS,if you rotated your tires.

Go to a shop with a TPMS tool or scanner with TPMS software, and have it reset.

Check the owner's manual for directions on how to reset the TPMS. You may have to deflate to a certain pressure before filling to proper pressure. There may also be a tire learning mode tied into the odometer's trip meter button. Hope this helps.

The TPMS is a pain in the you know what. Have you changed tire sizes? There could be a bad sensor and may need replaced. We continually get problems all the time with the TPMS. We have reset then they reset again.

It is on the same button as the Trip Odometer. Cycle through until you see Tire Reset and hold the button down.
